+== NAME
+
+nng_msg_set_pipe - set pipe for message
+
+== SYNOPSIS
+
+[source, c]
+-----------
+#include <nng/nng.h>
+
+void nng_msg_set_pipe(nng_msg *msg, nng_pipe p);
+-----------
+
+== DESCRIPTION
+
+The `nng_msg_set_pipe()` sets the pipe associated with message _m_ to _p_.
+This is most often useful when used with protocols that support directing
+a message to a specific peer.  For example the <<nng_pair#,nng_pair(7)>> version
+1 protocol can do this when `NNG_OPT__POLYAMOROUS` mode is set.
+
+NOTE: Not all protocols support overriding the destination pipe.
+
+== RETURN VALUES
+
+None.
+
+== ERRORS
+
+None.
